SPECIFICATION forming part of Letters Patent No. 668,059, dated February12, 1901. Application filed lune 13, 1900. Serial No. 20,130. (Nomodel.)

To (all w/m'nt t may concern:

Be it known that l, VILLIAM N. SHEEHAN, a citizen of the United States,residing at Salem, in the county of Columbiana and State of Ohio, haveinvented certain new and useful Improvements in Car-Axle Lubricators;and l do hereby declare that the following a full, clear2 and exactdescription of the same, reference being had to the annexed drawings,making a part of this specitication, and to the figures ot' referencemarked thereon, in Which- Figure l is a detached perspective view of theaxle-box, showing the lid closed. Fig. 2 is a longitudinal section ofthe box, showing a portion ofthe axle in proper relative position. Fig.3 is a detached view of the lid, showing a part broken away. Fig. et isa view showing the tube leadingl from the bottom of the auxiliaryoil-chamber and the material closing said tube.

Similar numerals ot' reference indicate corresponding parts in all thefigures of the drawings.

The present invention has relation to caraxle-box lids; and it consistsin the different parts and combination of parts hereinafter described,and particularly pointed out in the claim.

rlhe object of the present invention is to provide a mea-ns forautomatically supplying oil in case the bearing ot' the axle becomesheated from any cause, and the object is carried out as hereinafter moreparticularly described.

ln the accompanying drawings,l represents an axle-box, which isconstructed in the ordi nary manner, reference being had to properlyattaching any improved lid thereto.

To the axle-box lA is properly journaled the axle 2, said axle beingjournaled in the ordinary manner.

The particular formation of the box and the particular manner ofjournaling the axle have no particular reference to the presentinvention; but to carry out the object of the present invention it isnecessary to provide a box which is to be provided With a bearing forthe axle proper.

To the outer end of the box l is hinged the lid 3, which lid is providedupon its inner side with the inclined bottom 4, which inclined bottom islocated and arranged substantially as shown, and, as shown, it isarranged so as to provide an oil-chamber, such as 5, which oil-chamberis provided With a filling-aperture 6, said filling-aperture beingprotected by an ordinary screw-threaded cap 7 or its equivalent. Thebottom of the lid proper is provided With the short tube 8, which tubeis located and arranged substantially as shown, and, as shown, it islocated horizontally when the lid is brought into its normal position.

In use the lid 3 is so formed that it will close the outer end of thebox l when it is brought into the position illustrated in said Fig. l,and the chamber formed in the lid is supplied with a quantity of oil andthe oil held in the chamber by means of beeswax 9 or other like materialcapable of being melted at a low temperature of heat.

It will be understood that if the box becomes heated from any cause theheat will melt the beeswax or like material contained in the tube 8,thereby permitting the oil contained in the chamber of the lid to findits way to the axle 2.

It will be understood that the lid proper can be operated in theordinary manner in lubricating caraxles-that is to say, the lid may beopened and the oil placed in proper position7 after which the lid isclosed. It will also be understood that the chamber contained in the lidis to be supplied with oil at all times except when it is released byheat.

The object and purpose of providing an inclined bottom for theoil-chamber 5 and so arranging the tube S that it will be in ahorizontal position when the lid is in its normal position are toprevent the weight of the oil contained in the chamber from pressingdirectly against the fusible plug or filling contained in the tube S.

Having fully described my invention, what l claim as new, and desire tosecure by Letters Patent, is*

The combination of a car-axle box, a lid hinged thereto, and the lidprovided With au auxiliary oil-chamber separated by an inolned bottomfrom the axle-box, a tube leading from the inclined bottom of theauxiliary oil-chamber, and the tube normally closed by material capableof melting at a 10W degree of heat, substantially as and for the purposespecified.

In testimony that I claim the above I have hereunto subscribed my namein thepresenee of two Witnesses.

WILLIAM N. SI-IEEHAN.
